How to Choose a Nib Size:

• If you write small, go with Extra-Fine
• For everyday use, Fine is a great choice
• If you tend to write on the larger size, Medium is perfect and does provide a smoother ink flow
• Bold is for statements - Sign a check, write a header or show off your shimmering/sheening ink
• Stub nibs are used for an italic/calligraphy writing style with the down strokes being wide and the side strokes thin.
